Wind: Avoid spraying when wind is blowing towards sensitive crops.

Inversions: Don't spray during inversion conditions.

Temperature:

Delta T and relative humidity: Avoid application when Delta T is greater than

Soil moisture at application: Best results when soil moisture is not limiting growth.

9 ADJUVANTS:

Wetting agents: May be useful on hard to wet species.

Spray oils: Often used for summer spraying.

10 WATER QUALITY:

Hard water

Colloids

pH

11 COMPATIBILITY:

Trace elements.

Not compatible with zinc products (such as Zinc dextrose and Zinc heptahydrate), copper salts (such as sulphate) and manganese sulphate.

Do not use with hard water or water clarified with alum.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 20 to 1000 L/ha

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Aerial:

Carrier volume: >=20 L/ha

Nozzles: Coarse droplets.

Wind: 3-20 kph.

13 SPRAYER DECONTAMINATION:

Clean Up:

Remove filters and clean separately. Rinse with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Rinse with water.

Decontamination:

Remove filters and clean then soak in 500 mL household ammonia in 10 L water for 30 minutes.

Rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Fill with a 1% solution of ammonia and allow to stand for several hours. Triple rinse with water. Or use a commercial spray tank and equipment cleaner.

Rinse nozzles and filters in water and replace.

Don't use chlorine based cleaners.

14 HERBICIDE RESISTANCE:

Generally not a problem.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED: Wash out mouth with water. Do NOT induce vomiting; wash mouth with water and give some water to drink. Do NOT give anything by mouth to a semiconscious or unconscious patient.

If in EYES: Hold eyelids open and wash eyes with plenty of water for 5 minutes, remove contact lenses if present and wash for a further 10 minutes. See a doctor if symptoms persist.

If on SKIN: Remove contaminated clothing. Wash skin thoroughly with soap and water.

If INHALED: Remove patient to fresh air. See a doctor if symptoms persist.

Advice to doctor: Treat symptomatically.

27 ENVIRONMENTAL FATE:

Picloram component

Picloram is rapidly converted to the parent acids in soil, water, plants and animals.

Picloram is moderately to highly persistent in the soil environment, with field half-lives from 20 to 300 days and an estimated average of 90 days. Photo-degradation is significant only on the soil surface and volatilization is negligible. It is broken down mainly by microbial action.

It normally remains in the top 30 cm of soil but may be found deeper on soils with poor adsorption properties.

Picloram has a half life in water of 1 to 40 days in water depending mainly on sunlight intensity. It is broken down in water by ultra violet radiation and is stable to hydrolysis at neutral to alkaline pH.

Sunlight readily broke down Picloram in water, with a half-life of 2.6 days.

Herbicide levels in farm ponds were 1 mg/L directly following spraying, and decreased to 0.01 mg/L within 100 days, primarily due to dilution and the action of sunlight.

Ground water contamination is possible.

Breakdown in vegetation: Picloram is readily absorbed by plant roots, less so by the foliage, and is readily translocated throughout plants. It remains stable and intact in plants.

Replanting intervals - 12 months for most species to 4 years for some species. Accumulation in milk and tissues has not been found.

It can move in run-off water after heavy rainfall events as it dissolves in water rather than attaching to soil particles.



It has an EPA classification for soil mobility that ranges from
